Benefits of technology
The patent text describes a fuel cell control system that can operate each fuel cell even when there is an anomaly in one of the dispersed type fuel cell controllers. Additionally, the system can assign the role of each controller and reduce the load on them while increasing the reliability of the operation.
Problems solved by technology
However, when responding to the power requirement of each user by connecting multiple fuel cells, it can be difficult to manage the power supply efficiently, since, for example, an anomaly in the controller can halt the operation of multiple fuel cells.

Embodiment Construction
[0031]In the following, certain embodiments of the disclosure are described in detail so as to allow the disclosure to be readily practiced by the person having ordinary skill in the art. However, this is not to limit the present disclosure to particular modes of practice, and it should be appreciated that the disclosure encompasses all modifications, equivalents, and substitutes lying within the spirit and technical scope of the disclosure.
[0032]When an element is mentioned as being “connected” or “joined” to another element, it should be understood that, while the element can be directly connected or joined to the other element, one or more other elements can be present in-between.
[0033]In contrast, when an element is mentioned as being “directly connected” or “directly joined” to another element, this should be understood as meaning that there are no other elements in-between.
[0034]The terms used in the present specification are merely used to describe particular embodiments, and...

Abstract
Disclosed is a control system for a fuel cell system that includes at least two or more fuel cell groups which each have at least one fuel cell connected in parallel. The fuel cell control system comprises: a unit level controller configured to control an output of an individual fuel cell; a group level controller configured to determine the output distribution of the individual fuel cells within the fuel cell group based on the performance decrease rates of the individual fuel cells within the fuel cell group; and a system level controller configured to determine the total output of the fuel cell system according to the power demand for the grid and determine the output distribution for each of the fuel cell groups in correspondence to the total output.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of Korean Patent Application No. 10-2018-0161666, filed with the Korean Intellectual Property Office on Dec. 14, 2018, the disclosure of which is incorporated herein by reference in its entirety.BACKGROUND1. Technical Field[0002]The present disclosure relates to a control system for a fuel cell, more particularly to a system and a control method for operating the system in a stable manner by hierarchically controlling multiple parallel connected fuel cells.2. Description of the Related Art[0003]Generally, a fuel cell is a device for converting the energy of a fuel directly into electrical energy and generally involves a system that obtains electricity and heat through the arrangement of a pair of electrodes consisting of an anode and a cathode with an electrolyte placed in-between as well as through the electrochemical reactions of the ionized fuel gas.[0004]A polymer electrolyte fuel cell provides the ...
